The Eurasian three-toed woodpecker (Picoides tridactylus) is a medium-sized woodpecker that is found from northern Europe across northern Asia to Japan. The Eurasian three-toed woodpecker was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. He coined the binomial name Picus tridactylus. The type locality is Sweden. The specific epithet is from the Ancient Greek tridaktulos meaning "three-toed" (tri- is "three-" and daktulos is toe). The species is now placed in the genus Picoides that was introduced by the French naturalist Bernard Germain de Lacépède in 1799. The Eurasian three-toed woodpecker was formerly considered conspecific with the American three-toed woodpecker (Picoides dorsalis).

With luck
About 10% of wildlife watchers report a Eurasian Three-toed Woodpecker sighting in Novosibirsk on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 91st most-seen of the 123 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
February
In that month about 20% of wildlife watchers report a Eurasian Three-toed Woodpecker in Novosibirsk on a given day, against under 5% in March–August and November, the lowest months. That is one of Novosibirsk's driest months, with about 25 mm of rain against 75 mm in July.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Eurasian Three-toed Woodpecker sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Eurasian Three-toed Woodpecker is recorded against all the birds logged in Novosibirsk (10 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
